BACKGROUND 1. Technical Field

The disclosure relates to a vehicle seat.

2. Description of Related Art

There has been known a vehicle seat including a seat pad that supportsan occupant, a through-hole formed so as to extend through the seat padin a direction from an occupant sitting side to a side opposite to theoccupant sitting side, and a frame member attached to an opening end ofthe through-hole on the occupant sitting side (see French PatentApplication Publication No. 3011207). The frame member has an openingconfigured such that a fixation connecting portion (connector) of achild safety seat for ISOFIX is inserted into the opening. The ISOFIX isthe international standard of a method for fixing a child safety seat toa vehicle.

SUMMARY

However, the vehicle seat described in French Patent ApplicationPublication No. 3011207 is formed as follows. In a state where the framemember is attached to a wire member, a seat pad is formed around thewire member, for example, by foaming urethane foam or the like, andthen, the frame member is attached to a locking member. Thus, theattachment of the frame member is complicated.

The disclosure provides a vehicle seat in which a frame member is easilyattached with a simple structure.

An aspect of the disclosure relates to a vehicle seat. The vehicle seatincludes a seat pad configured to support an occupant, the seat padhaving a through-hole provided so as to extend through the seat pad in adirection from an occupant sitting side toward a side opposite to theoccupant sitting side; and a frame member attached to an opening end ofthe through-hole on the occupant sitting side, the frame member havingan opening configured such that a fixation connecting portion of a childsafety seat is inserted into the opening. The frame member is providedwith a locking portion locked to the seat pad. The seat pad includes alocking pad portion constituting a part of an inner wall surface of thethrough-hole, a wire member is embedded in the locking pad portion, andthe locking portion of the frame member is locked to the locking padportion.

In the vehicle seat, the locking portion of the frame member is lockedto the locking pad portion, of the seat pad, in which the wire member isembedded, the frame member having the opening configured such that thefixation connecting portion of the child safety seat for, for example,ISOFIX is inserted into the opening. That is, the frame member isattached to the locking pad portion of the seat pad, which has beenformed with the wire member being embedded therein. Therefore, forexample, it is not necessary to form the seat pad during the attachmentof the frame member, unlike the related art, and the frame member can beeasily positioned and attached. Thus, with a simple structure, theattachment of the frame member in the vehicle seat is easily performed.

In the vehicle seat according to the above aspect, the frame member mayinclude a frame body portion having the opening, a locking extensionportion extending from the frame body portion toward the seat pad, andthe locking portion extending from the locking extension portion. Inthis case, the attachment of the frame member in the vehicle seat isfurther easily performed.

At least a part of the locking pad portion may be disposed between theframe body portion and the locking portion in the frame member, and thelocking portion may be locked to the locking pad portion from the sideopposite to the occupant sitting side. In this case, the locking portionof the frame member can be sufficiently locked to the locking padportion. Further, the positioning of the frame member with respect tothe locking pad portion is easily performed.

At least the part of the locking pad portion may be sandwiched betweenthe frame body portion and the locking portion in the frame member. Inthis case, the positioning of the frame member with respect to thelocking pad portion is further easily performed.

The locking portion of the frame member may include a projecting portionprojecting toward the locking pad portion. In this case, the lockingportion of the frame member can be easily and sufficiently locked to thelocking pad portion.

The projecting portion of the locking portion of the frame member mayproject toward the wire member embedded in the locking pad portion. Inthis case, the locking portion of the frame member can be further easilyand sufficiently locked to the locking pad portion.

At least a part of the locking pad portion may be covered with acovering material covering the seat pad, and at least a part of thecovering material covering the locking pad portion may be disposedbetween the locking pad portion and the locking portion of the framemember. In this case, the covering material can prevent the locking padportion from being exposed to the outside, thereby making it possible toimprove external appearance and a design property. Further, at least apart of the covering material covering the locking pad portion can besufficiently held between the locking pad portion and the lockingportion of the frame member.

The seat pad may be a cushion pad disposed inside a seat cushionconfigured to support buttocks of the occupant. In this case, the framemember is easily attached to the seat cushion.

The cushion pad may include a pad body portion, and a pad projectingportion projecting from the pad body portion toward a seatbackconfigured to support a back of the occupant, and the through-hole andthe locking pad portion may be provided in the pad projecting portion.In this case, the frame member is easily attached to the seat cushion.
